1. Product features of grouting materials
Good durability: 10,000 fatigue tests, 10,000 freeze-thaw cycle tests, no significant change in strength, good anti-permeability, anti-freeze, and anti-corrosion properties Excellent performance, no corrosion of steel bars.
, does not contain chloride, and has no corrosive effect on equipment and steel bars.
Easy to use: The finished product is dry-mixed mortar, which can be used after adding water according to regulations at the construction site.
The effective bearing area of the upper surface of the bearing grouting material is greater than %.
, No corrosion to steel bars.
2. Scope of application of grouting material
Bearing grouting material is suitable for prefabricated simply supported box beam paving for passenger dedicated lines.
The bearing grouting material is suitable for emergency repair, bridge bearing anchor grouting, track anchor grouting, etc.
3. How to use grouting material
Basic treatment: Chisel the surface of the supporting cushion at the installation part of the bearing, clear the debris in the reserved holes, install the grouting template, the template and the top surface of the cushion Reliable measures should be taken to prevent grout leakage during gravity grouting. The base layer to be grouted must be cleaned of dust, oil, other dirt and other substances that are not conducive to bonding. The base layer should be moistened with clean water until it is saturated, but no open water should be left during construction.
Lift the prefabricated box beam (with supports), place the box beam on the temporary support jack, and adjust the fulcrum elevation of the beam body through the jack.
After the beam body is in place, a gap of ~ should be reserved between the base plate of the support and the support cushion of the pier and platform to facilitate the grouting of the support by gravity grouting.
Use gravity grouting to fill the gaps at the bottom of the support and the anchor holes. The grouting process should be from the center of the support to the surrounding areas until the grouting material is completely filled from the gap between the formwork and the bottom plate of the support. The required slurry volume should be initially measured before grouting. The actual amount of grouting grout should not have too large an error with the calculated value to prevent lack of grout in the middle.
. The slurry is prepared according to powder: water = : . (weight ratio)
After the grouting material reaches the specified strength, remove the formwork, check whether there is grout leakage, and replenish the grouting area.
Tighten the foot bolts of the lower support plate, remove the angle steel connecting the upper and lower supports, remove the temporary jack, and install the support steel enclosure. Machinery and tools should be rinsed with water immediately after construction.
The construction time depends on the ambient temperature. At ℃, it will be used up within minutes after the mixing is completed. Since temperature has a great influence on the setting time and early strength of the product, users are required to strictly follow the "Technical Methods for Construction of Support Grouting Materials" to carry out construction and maintenance in low temperature (-℃) or high temperature (℃) environments to meet construction requirements. . Do not add water to the slurry that cannot regain fluidity and mix again before use.
[Example] In the year and month, after the concrete was poured on the underground floor of a certain project, it was found that the beams B and deep along the axis and the axis had exposed reinforcements throughout the entire span, there was no protective layer at the bottom of the beams, and there was vibration leakage in the concrete at the column heads. . Since the steel bars at the bottom of the beam are tightly arranged and the gaps are small, if sprayed concrete is used to repair them, the concrete will rebound too much and the concrete will still not be able to enter the small gaps, and the strength of the repaired concrete will not meet the original concrete design requirements. If polymer concrete is used for repair, it will also be limited by construction conditions and it will not be easy to ensure close integration with the old concrete. Therefore, the best repair solution is still to use grouting material for repair. Since there are many vertical and horizontal reinforcing bars protruding from the bottom and sides of the beam, a major difficulty in repair is to set up the formwork.
